GEORGE J. BOHLMAN, OF MEDFORD, MASSACHUSETTS, ASSIGNOR TO AMERICAN WATER SUPPLY COMPANY OF NEW ENGLAND, OF BOSTON, MASSACHUSETTS, A CORPORA- TION OF MAINE.

BOTTLE-CLOSURE.

Specification of Letters Patent.

Application filed February 13, 1915. Serial No. 8,104.

0 till whom it may concern Be it known that I, GEORGE J. BOHLMAN,

a citizen of the United States, residingat Medford, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Bottle-Closures, of which the following is a specification.

This invention relates to paper bottleclosures especially adapted for milk bottles and the like. I I

The invention has for its object the construction of a closure adapted to extend over the open mouth of a bottle, and also to extend down over and embrace the upper endportion of the bottle, thereby to close said open mouth and also entirely cover the endportion of the bottle surrounding said mouth to protect it from dust, dirt, etc., so that when removed from the bottle, a clean edgeportion will be exposed, over which to pour the milk, said closure having a fasteningdevice associated with its downwardly extended embracing-portion by which it is held in contracted form to snugly engage the bottle, thereby to hold the closure in posi-.

tion thereon.

Another object of the invention is the construction of a closure, as aforesaid, having a fastening-device which may be manipulated easily and quickly by the pressure of the thumb while the embracing portion thereof is held in firm engagement with the bottle by thehand.

Another object of theinvention is the construction of a closure, which, while suitably closing the open mouth of a bottle, yet provides for ventilating the bottle, so that in case the milk is pouredinto the bottle at too high a temperature, it will be permitted to cool quickly.

These and other features of the invention, in so far as they are embodied structurally, will be hereinafter described.

Figure 1 is a side-elevation of a bottleclosure embodying this invent-ion, arranged on a bottle. Figs. 2 and 3 are similar views of the closure removed from the bottle. Fig. 4 is a horizontal section of Fig. 1 showing particularly the fasteni-ngdevice for the downwardly extended embracing portion. Fig. '5 is a fragmentary view showing the fastening-device in engaging position. Fig. 6 is a plan view of the blank of which the bottle-closure is composed.

Referring first to Fig. 6, the blank therein may be secured together.

shown consists of a circularly formed piece of paper of a good quality as regards strength and thickness, which is coated with a sizing or otherwise treated to make it waterproof. This circular piece is slitted radially inward from its edge for a considerable distance, thus to provide an imperforate central-portion l and a plurality of tabs 2. The radial slits separating the tabs are indicated at 3. The end-portions of these tabs, or at least some ofthem, are, or may be reduced in width by cutting off the corners, as indicated at 4. The circular central-portion l is made of suflicient area to cover the open mouth of the bottle, and to extend over the upper end of the wall surrounding said mouth, and the tabs 2 are bent downwardly at right angles to the centralportion or thereabout. The tabs are made long enough to extend downward for a considerable distance and when thus bent down wardly, they are caused to overlap one another. Such overlapping may be in a regular order, or otherwise, but in any event, an embracing-portion is produced for the upper end-portion of the bottle which is approximately cylindrical. The embracing-portion thus formed of the tabs is substantially tight, as the tabs overlap one another for their entire length. The several tabs are adhesively secured together, so thatthe embracing-portion becomes a solid structure with the exception of two adjacent tabs which are not adhesively secured together along one of the radial slits, these two tabs forming the end tabs of the circular series. At such point, a fasteningdevice is employed by which these end-tabs of the series The fasteningdevice, here shown, consists of a metallic plate 5, having a plurality of prongs 6 with sharp points, and said prong-plate is attached at one end to one of the tabs and its other end extends over the adjacent tab for attachment thereto. This form of fastening-device with its sharp-pointed prongs,

when attached to one of the tabs, may be permanently arranged on the bottle. By cutting oil the corners of the tabs some of the surplus paper is removed, so that the downwardly extended embracing-portion is not of undue thickness, and. when its component parts are adhesively secured together is not of undue stiffness. Until the u'nattached tabs are attached together the embracing portion will' be distended more or less, but when the closure is arranged on the bottle, said embracing-portion may be grasped by the hand and contracted and brought into firm engagement with the upper end-portion of the bottle, and when in such condition, the fastening-device will be manipulated and the unattached tabs attached together thus firmly andpermanently securing the closure upon the bottle. This closure while tight enough for all practical purposes, yet does provide some ventilation for the bottle which is an advantage, as oocasionally the milk is poured into the bottle at too high a temperature, and such ventilation provides for the cooling of the milk.

I claim 1. The bottle-closure herein described, consisting of a piece of paper of circular form radially slitted to form a circular cen tral-portion and a plurality of tabs, said tabs being bent downwardly and overlapped to form an embracing-portion and adhesively secured together with the exception of two adjacent tabs of the series, and a fastening-device connected with one of said unattached tabs and arranged to extend over and to engage the other. unattached tab.

2. The bottle-closure herein described, consisting of a piece of paper of circular form radially slitted to vform a circular central-portion and a plurality of tabs, said tabs being bent downwardly and overlapped to form an embracing-portion and adhesively secured together with the exception of two adjacent tabs of the series, and a pronged plate attached to one of said tabs and extended over and adapted to engage the other tab.

3. The bottle-closure herein described, consisting of a piece of paper of circular form radially slitted to form a circular central-portion and a plurality of tabs, the end-portions of some of said tabs being reduced in width, said tabs being bent-downwardly and overlapped to form an embracing-portion and adhesively secured together with the exception of two adjacent tabs of the series, and a fastening-device connected with one of said unattached tabs, and arranged to extend over and to engage the other unattached tab.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
